Key Takeaway
Interpret SUCRA rankings cautiously; no significant OS differences were found between these HCC regimens.

This network meta-analysis compared the efficacy of three systemic therapies—atezolizumab plus bevacizumab, lenvatinib, and sorafenib—in patients with unresectable hepatocellular carcinoma, synthesizing data from 11 studies. The primary outcome was overall survival (OS). No statistically significant differences in OS were found between the regimens. The hazard ratio for atezolizumab plus bevacizumab versus lenvatinib was 0.98 (95% CI: 0.24-4.10). For atezolizumab plus bevacizumab versus sorafenib, the HR was 1.4 (95% CI: 0.21-9.87). For lenvatinib versus sorafenib, the HR was 1.41 (95% CI: 0.38-5.14). All confidence intervals were wide and crossed 1.0, indicating substantial uncertainty. A SUCRA ranking analysis suggested atezolizumab plus bevacizumab had the highest probability of being ranked first for OS, followed by lenvatinib, then sorafenib. This ranking suggests a clinical trend but does not establish definitive superiority. Safety, tolerability, and adverse event data were not reported in this analysis. Key limitations include the inconsistent results across prior studies, which the authors note make existing findings 'not completely clear.' The wide confidence intervals in this analysis further limit the certainty of the comparative efficacy estimates. Funding and conflicts of interest were not reported. For clinical practice, this analysis provides a structured, indirect comparison but does not offer high-certainty evidence to favor one regimen over another for overall survival in unresectable HCC. The SUCRA ranking may inform hypothesis generation for future research but should not be used for definitive treatment selection.

This study compared the effectiveness of three specific treatments for patients with unresectable hepatocellular carcinoma. The analysis combined data from eleven existing studies to evaluate lenvatinib, the combination of atezolizumab and bevacizumab, and sorafenib. The primary goal was to determine if one option offered better overall survival than the others.

The results indicated that overall survival was similar across all three groups. Specifically, there were no statistically significant differences in survival time when comparing atezolizumab plus bevacizumab against lenvatinib or sorafenib. While atezolizumab plus bevacizumab had the highest probability of being ranked as the top option, this suggests a clinical trend rather than definitive superiority over the other drugs.

Safety information regarding adverse events, serious reactions, or discontinuations was not reported in this analysis. Because the hazard ratios were not statistically significant, readers should understand that no single drug proved definitively better for survival. This research provides clearer insights into treatment options but does not change current practice due to the inconsistent results found in existing studies.

What this means for you:
Three drugs showed similar survival for unresectable liver cancer; results remain uncertain.

INTRODUCTION: Globally, hepatocellular carcinoma (HCC) ranks as the third most common cause of cancer-related death. The five-year overall survival (OS) rate for patients with unresectable HCC is only 12%. Currently, systemic therapies have become the primary treatment options for unresectable hepatocellular carcinoma. Studies comparing the efficacy of first-line treatments including lenvatinib, atezolizumab plus bevacizumab, and sorafenib have shown inconsistent results. There remains a need for updated comparative evidence on cross-mechanism therapy regimens for unresectable disease, as existing findings are still not completely clear. This network meta-analysis aims to provide clearer insights into which treatment offers greater efficacy for patients with unresectable HCC. METHODS: This study was conducted following the 2022 PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Literature searches were performed using PubMed, ScienceDirect, Google Scholar, the Cochrane Library, SpringerLink, and EBSCO to gather studies comparing lenvatinib, atezolizumab plus bevacizumab, and sorafenib for the management of unresectable HCC. The risk of bias was assessed using the Newcastle-Ottawa Scale (NOS). Overall survival (OS) was analyzed using R statistical software (version 4.4.0). RESULTS: Eleven studies reporting overall survival (OS) were included in the OS analysis comparing lenvatinib, atezolizumab plus bevacizumab, and sorafenib in the treatment of unresectable HCC. The network meta-analysis showed no significant OS differences between atezolizumab plus bevacizumab and lenvatinib (HR: 0.98; 95% CI: 0.24-4.10) or sorafenib (HR: 1.4; 95% CI: 0.21-9.87). Furthermore, there was no significant difference in OS between lenvatinib and sorafenib (HR: 1.41; 95% CI: 0.38-5.14). Based on the SUCRA plot in this meta-analysis, atezolizumab plus bevacizumab showed the highest probability of being ranked first among the three therapies. Lenvatinib had the highest probability of being ranked second, while sorafenib was more likely to be ranked third. CONCLUSION: Atezolizumab plus bevacizumab, lenvatinib, and sorafenib demonstrated similar therapeutic efficacy based on overall survival. Although the hazard ratios (HRs) were not statistically significant, the SUCRA ranking suggested a clinical trend favoring atezolizumab plus bevacizumab.
